How to Waterproof a Masonry Wall
To waterproof a masonry wall, it is important to seal and protect the brick on a home’s exterior.
Unsealed brick can absorb water, leading to structural damage and cracking.
It can also result in the formation of efflorescence, a white powdery substance, and fading of the brick color due to exposure to UV light, rain, snow, and ice.
Unsealed brick is susceptible to spalling and crumbling, and it can provide a breeding ground for mold, mildew, weeds, and grass.
To prevent these issues, different types of brick sealants can be used, such as Silane/Siloxane sealers.
High gloss sealants can provide a glossy finish, while matte sealants offer protection without significantly altering the brick’s appearance.
Wet-look sealers give the brick a darkened and moistened appearance.
By selecting the right brick sealant for the specific purpose and applying it properly, damage from moisture, efflorescence, fading, crumbling, spalling, mold, mildew, weeds, and grass can be effectively prevented.

Did You Know?
1. Did you know that the oldest known waterproof masonry construction dates back over 4,000 years? The Great Bath of the ancient city of Mohenjo-daro in modern-day Pakistan was made of tightly sealed bricks and bitumen to prevent water leakage.
2. The concept of waterproofing masonry walls can be traced back to ancient Rome, where the Romans used a special mortar mixture that contained volcanic ash known as “pozzolana.” This mixture not only hardened quickly but also became highly resistant to water infiltration.
3. In the early 1800s, a French chemist named Louis Nicolas Vauquelin discovered that linseed oil, when combined with certain metallic oxides, formed an effective waterproofing agent. This groundbreaking discovery eventually led to the development of modern waterproof coatings that are used extensively today.
4. One little-known technique for waterproofing masonry walls involves using a substance called “silane.” Silane is a clear liquid that bonds chemically with the minerals in masonry, effectively creating a waterproof barrier without altering the appearance of the wall.
5. Muralists and street artists often use a product called “hydrophobic paint” as a form of waterproofing for their artwork on masonry walls. This special paint repels water, preventing color fading and deterioration caused by rain or other environmental factors.
Absorption Of Water Leading To Structural Damage
Waterproofing a masonry wall is crucial for protecting a home’s structural integrity. Sealing and waterproofing brick on the exterior is important in order to prevent water absorption. Unsealed brick allows water to infiltrate its surface, which can lead to severe problems such as structural damage and cracking.
The continuous exposure to water weakens the masonry wall over time. This is particularly damaging in regions with freezing temperatures. When the water trapped within the brick freezes, it expands and exerts significant pressure on the material. The repeated freeze-thaw cycles can result in cracks and fractures, causing irreversible damage to the masonry wall.
Formation Of Efflorescence On Unsealed Brick
Efflorescence is a common problem associated with unsealed brick. It refers to the appearance of a white, powdery substance on the surface of the brick. This phenomenon occurs when water infiltrates the brick and carries along minerals, primarily salt, from within. As the water evaporates, the salt is left behind, forming a crystalline deposit on the surface.
Efflorescence not only detracts from the aesthetic appeal of the brick but also indicates that there is a moisture problem. Furthermore, if left untreated, the constant presence of moisture can result in structural issues as the salts can cause the brick to deteriorate over time. Sealing the brick effectively prevents water penetration, minimizing the occurrence of efflorescence and safeguarding the brick against long-term damage.
Fading Of Brick Color Due To Environmental Factors
In addition to the structural concerns caused by water absorption, unsealed brick is also susceptible to fading. Exposed to environmental factors such as UV light, rain, snow, and ice, the vibrant colors of the brick can gradually fade, losing their original charm and appeal. This can significantly affect the overall aesthetics of a home’s exterior.
Sealing the brick not only provides protection against water but also acts as a barrier against the harsh elements that contribute to color fading. By creating a shield on the brick’s surface, a quality sealant helps maintain the brick’s original color for a longer period. This is particularly important for homeowners who wish to uphold the visual attractiveness and curb appeal of their property.
- Sealed brick is protected against water absorption and color fading
- Quality sealant acts as a barrier against environmental elements
- Maintains the original color and appeal of the brick for longer
“Sealing the brick is essential in preserving its vibrant color and visual appeal.”
Susceptibility Of Unsealed Brick To Spalling And Crumbling
Unsealed brick is more prone to spalling and crumbling compared to its sealed counterparts. Spalling occurs when water seeps into the brick and gradually erodes its surface. This can lead to portions of the brick breaking off and crumbling, compromising the integrity of the masonry wall.
Sealing the brick effectively protects it from water infiltration, reducing the risk of spalling and crumbling. By creating a barrier, the sealant prevents water from penetrating the brick’s surface and causing the gradual deterioration that leads to spalling. Regularly sealing the brick prevents such damage and extends the lifespan of the masonry wall.

Sealing the brick is essential to preserve its integrity and extend its lifespan.
Growth Of Mold, Mildew, Weeds, And Grass On Unsealed Brick
Unsealed brick is a breeding ground for mold, mildew, weeds, and grass. The presence of moisture, particularly in humid environments, creates an ideal environment for these unwanted organisms. Mold and mildew not only affect the appearance of the brick but also pose health risks to home occupants.
Sealing the brick inhibits the growth of these organisms by creating a protective barrier against moisture. By eliminating the conditions necessary for their development, a sealed masonry wall effectively reduces the growth of mold, mildew, weeds, and grass. This has a positive impact on the exterior aesthetics of the home and contributes to a healthier living environment.
Understanding Different Types Of Brick Sealants
When it comes to sealing masonry walls, it is essential to understand the different types of brick sealants available. One commonly used type is Silane/Siloxane sealers. These sealants penetrate deep into the pores of the brick, creating a hydrophobic barrier that repels water while still allowing the brick to breathe. Silane/Siloxane sealers are effective in protecting against water damage without altering the appearance of the brick significantly.
Another option to consider is high gloss sealants, which provide a glossy finish to the brick surface. These sealants enhance the brick’s natural colors and give it a sheen, enhancing the visual appeal of the masonry wall. For those who prefer a more subtle approach, matte sealants can be used. These sealants offer protection without significantly altering the appearance of the brick, maintaining its original look.
Differentiating between shiny and wet look sealers is also crucial. Shiny sealers provide a glossy appearance while wet look sealers create a darkened and moistened appearance on the brick. Understanding the difference between these sealers allows homeowners to choose the desired aesthetic effect for their masonry walls.
To summarize,
- Silane/Siloxane sealers are commonly used and penetrate deep into the brick to repel water without altering the appearance significantly.
- High gloss sealants provide a glossy finish, enhancing the brick’s natural colors and visual appeal.
- Matte sealants offer protection without altering the appearance of the brick.
- Differentiating between shiny and wet look sealers allows homeowners to select the desired aesthetic effect.
Properly waterproofing a masonry wall by sealing and waterproofing brick on a home’s exterior is an essential step to prevent various issues such as structural damage, efflorescence, color fading, spalling, and the growth of mold, mildew, weeds, and grass. Understanding the various types of brick sealants available allows homeowners to select the most suitable option for their specific needs. By implementing proper sealing techniques and using quality sealants, homeowners can ensure the longevity and aesthetics of their masonry walls.
